7‐Aryl‐1,3,5‐cycloheptatrienes react intermolecularly with methylenecyclopropanes in a triple gold(I)‐catalyzed reaction to form cyclopentenes. The same formal (4+1) cycloaddition occurs with cyclobutenes. Other precursors of gold(I) carbenes can also be used as the C1 component of the cycloaddition.
7-芳基-1,3,5-环庚三烯在三重金 (I) 催化反应中与亚甲基环丙烷发生分子间反应,形成环戊烯。环丁烯也发生相同的正式 (4+1) 环加成反应。金(I)卡宾的其他前体也可以用作环加成的C 1组分。
